CC   -!- FUNCTION: This b-type cytochrome is tightly associated with the
CC       reaction center of photosystem II and possibly is part of the
CC       water-oxidation complex (By similarity).
CC   -!- SUBUNIT: Heterodimer of an alpha subunit and a beta subunit (By
CC       similarity).
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Single-pass
CC       membrane protein (By similarity).
CC   -!- SIMILARITY: Belongs to the PsbE/PsbF family.
